Does A Can or Suppresor Increase Back Pressure and Decrease Velocity??? Well????

[QUOTE="Rocketeer77, post: 2440149, member: 119378"] The projectile departing the chamber going into the barrel has a shock wave going ahead of it and that's identical with or without a suppressor. That pulse of compressed air being pushed out the barrel has nothing whatsoever to do with the imaginary gas leakage past the projectile. There will be some initial blow by until the projectile is fully sealed into the rifling. We're actually talking about two entirely different topics here, the original question was gas leakage past the projectile. That initial query was hopefully answered and now we're talking about a gas column being pushed out of the barrel by the projectile. With a suppressor the overall resistance will be slightly higher, yet empirical data with respect to comparison velocities proves this additional air resistance is negligible. Decades working with experts in thermodynamics taught me some basic knowledge of what's probably happening when that trigger is pulled. The measured velocities between unsuppressed and suppressed rifles is minimal and that was the original question? [/QUOTE]
